Because of the speed of dialup, I go the extra step of backing up
/var/lib/apt/lists, too, just in case that directory's contents
somehow get zapped in the process. Afterward, I run a quick "diff"
comparison to see if anything notable needs put back in place.

Most times nothing needs changed after previously favored
/etc/apt/sources.list lines are put back in place. If something does
need replaced, it's most likely due to a mistake on my part.

Backing up that lists directory is just a precautionary step I have to
take relative to my usage circumstances. It only takes 2 seconds to
both create and then later delete. In return, the step can save (and
HAS SAVED) many HOURS of wear and tear on my computer, my Internet
service provider's servers, AND MOST IMPORTANTLY (*to me*), whatever
VOLUNTEER Debian repository host(s) might be affected each time.
